My perception, visions and notions.....

Google has added the support for Java in their Application Engine. With this new feature they have provided a marvelous tool for the GWT developers which is called the “Google plugin for Eclipse“. This plugin would help you to create, compile a GWT application and deploy it to the Google App Engine with few clicks only.
I will show you how to install this plugin for Eclipse:

For Eclipse 3.3 (Europa):

• Go to Help menu.
• Select Software Updates.
• Select Find and Install. In the dialog that appears, select Search for new features to install and click Next.
• Click New Remote Site.
• Enter a name for the update site (e.g. Google Update Site for Eclipse 3.3) and the following value for the URL: http://dl.google.com/eclipse/plugin/3.3. Click OK.
• The newly-added site is checked to indicate that it will be searched for features to install. Click Finish.
• In the subsequent Search Results dialog, select the checkbox for the update site (e.g. Google Update Site for Eclipse 3.3). This will install the plugin, a Google App Engine Java SDK and a Google Web Toolkit SDK. Click Next.
• select I accept the terms in the license agreements. Click Next.
• If you then select finish, there would be a prompt shown. The plugin is not signed so you must acknowledge that you are installing an unsigned feature. Click Install All.
• You will then be asked be asked if you would like to restart Eclipse. Click Yes.

For Eclipse 3.4 (Ganymede):

• Go to Help menu.
• Select Software Updates.
• In the Available Softwares tab, click on the “add site” button.
• Put “http://dl.google.com/eclipse/plugin/3.4″ , click ok.
• Back in the Available Software view, you should see a new update site named Google Update Site for Eclipse 3.4. Select the checkbox next to the new update site. This will install the plugin, a Google App Engine Java SDK and a Google Web Toolkit SDK. Click Install.
• Review the features that you are about to install. Click Next.
• Select I accept the terms in the license agreements. Click Next.
• You will then be asked if you would like to restart Eclipse. Click Yes.

If you downloaded the GWT package and the Google-App-Engine SDK seperately, then you would just have to install the core plugin only. And then, you have to go to the preference and set the paths of both the GWT package and the App Engine SDK by selecting “Google” from the left tree panel of the preference dialog.
You are done. Now You are ready to create, develop, run, debug and deploy the GWT application with a great ease.
